Earlier this month, Microsoft announced a program that would give iOS app developers a way to purchase a version of Windows 8, plus a version of Parallels Desktop 8 for just $25, as an incentive for them to port their iOS creations to Windows 8, or to make all new apps. That offer quickly sold out but Microsoft is now going to give iOS developers a second chance to get in on this cheap software deal.

As with the previous offer, the $25 cost for the Windows QuickStart package, which would normally cost close to $200, is being donated to charity, specifically to code.org, Khan Academy or Watsi.org. iOS developers who cannot attend the builder events can still get the $25 Windows Quickstart software bundle at swish.com, but the package won't actually ship until sometime in early June.
